Silicon Nitride Ceramic:

When Backland retired in 1939, his son George Washington Backland had no intention of doing business, and the company was sold to Union Carbide for $16.5 million (equivalent to $200 million today). In 1945, one year after Baekeland's death, the annual output of plastics in the United States exceeded 400,000 tons, and in 1979 it surpassed the representative of the industrial era-steel. At the exhibition at the Science Museum in London, Beckland's great-grandson Hugh Karak held a urea-formaldehyde plastic phone from the 1930s in one hand and a cell phone made of biodegradable plastic in the other. The rapid development of the plastic industry has also brought about a series of social problems caused by waste plastics and waste plastics. The application of plastic products has penetrated into every corner of society, from industrial production to food, clothing, housing and transportation, plastic products are everywhere. People are beginning to discover that plastic waste has quietly poured into us, seriously affecting our health and living environment. For example, some agricultural land has begun to reduce production due to the impact of waste mulch film, and the "white pollution" caused by waste plastics has begun to give people headaches. , Lunch boxes that do not rot or decompose cannot be effectively recycled, and plastic garbage for domestic use cannot be dealt with. The rapid increase in plastic waste and the social and environmental problems caused by it are placed in front of people, where people all over the world live and live.
